The Oil and Gas industries often uses hydrogen to upgrade heavy crude oils into refined fuels, and help to meet transportation fuel specifications. Hydrogen can also be used to de-sulphurize fuels, to heat-treat metals, and to test for leaks.

The Metal Fabrication industry often mixes hydrogen with argon as a shielding gas for TIG and plasma  welding of stainless steel. Hydrogen can also be combined with oxygen for underwater flame-cutting.

We deliver gaseous and compressed hydrogen in a variety of cylinders, vessels and containers to fit your  precise application needs.
